Weak type (1,1) jump inequalities in a nonsymmetric Gaussian setting
Valentina Casarino, Paolo Ciatti, Peter Sjögren
We prove that the jump quasi-seminorm of order for a general Ornstein--Uhlenbeck semigroup in defines an operator of we…
Variational inequalities for the Ornstein--Uhlenbeck semigroup: the higher--dimensional case
Valentina Casarino, Paolo Ciatti, Peter Sjögren
We study the -th order variation seminorm of a general Ornstein--Uhlenbeck semigroup in , taken with respect to . We prov…
New sharp bounds for the Jacobi heat kernel via an extension of the Dijksma-Koornwinder formula
Adam Nowak, Peter Sjögren, Tomasz Z. Szarek
We obtain sharp estimates for the Jacobi heat kernel in a range of parameters where the result has not been established before. This extends and completes an earlier result due to…
Boundedness from H^1 to L^1 of Riesz transforms on a Lie group of exponential growth
Peter Sjögren, Maria Vallarino
Let be the Lie group given by the semidirect product of and endowed with the Riemannian symmetric space structure. Let be a distinguished basis of l…
